The Message Rules window can be opened by clicking your cursor arrow on
"Tools" in the menu bar and selecting "Message Rules"
from the drop-down menu.

MAIL RULES -
Create rules which can be applied to e-mail messages. For example,
you can create a rule that deletes unwanted e-mail with certain words
in the subject or a rule that forwards messages from a certain sender
to another e-mail address. You can filter e-mail messages using various
criteria.

NEWS
RULES -
Similar to Mail Rules, you can create rules for reading news messages.
There are options for highlighting, flagging and marking messages
as read. You can also delete messages older than a certain number
of days or messages from certain senders.

BLOCKED SENDERS -
Automatically move messages from specific e-mail addresses or entire
domains to the "Deleted Items" folder so they don't show up in your
Inbox. You can also choose to block mail messages, news messages or
both mail and news messages from these senders. For example, if you
are getting spam from a certain domain, just add that domain to your
Blocked Senders.
